| 摘 要： | 以大豆片为原料,利用双螺杆挤压膨化机进行实验研究,大豆片经挤压膨化、脱脂、高温脱溶得高温豆粕,研究不同物料含水量、套筒温度、模孔孔径和螺杆转速对酶解高温豆粕肽得率的影响。通过单因素和正交实验,确定最佳的挤压膨化参数为:物料含水量20%,套筒温度60℃,螺杆转速100r/min,模孔孔径15mm,肽得率36.88%。挤压膨化技术可以有效提高豆粕利用率,为今后工业化生产提供理论依据。 |

| Abstract: | The extruding experiment by two-screws extruder was studied with the soy flake as materias.The high denatured soybean meal was obtained from soybean flakes by extrusion,degreasing and desolventizing at high temperature.The effect of moisture content of materials,barrel temperature,the rotating speed of screws and die diameter on the peptide yield of enzymatic high denatured soybean meal were studied.Single factor experiments and orthogonal test were applied to analyze the factors.The contribution rate of factor was as follow:moisture content of materials 20%,barrel temperature 60℃,the rotating speed of screws 100r/min and die diameter 15mm,the peptide yield can reached at 36.88%.Extrusion can effectively improve the utilization of soybean meal to provide a theoretical basis for future industrial production. |
